I have noticed a drop up to 2/3 in backup performance on HP-UX 11.31 systems where PHKL_41700 is installed.  A support case at HP provided the follwing information:

PHKL_41700 introduced behavior whereby on systems that do not enable high resolution timers, applications that use the select(2) system call as a timers may suffer performance degradation. If the performance degradation disappears after setting the kernel tunable:

hires_timeout_enable=1

Then the performance degradation observed is caused by the changes introduced in the select(2) system call code path provided by PHKL_41700.

This behavior is known to affect the performance of DataProtector, Quest Shareplex, Oracle SQL, Veritas Cluster Server, xntp (Network Time Protocol) and xterm(1) commands. Furthermore, any application that uses the select(2) system call with zero timeout and a value for nfd > 0 will experience this behavior.

To work...

IDC approached Symantec, unsolicited, for a briefing on V-Ray. They were looking to create an Insight Report for their customers as they had so many inquiries around V-Ray. You’ll find this to be a very comprehensive and technical write up that shows NetBackup’s leadership in virtual machine protection with VMware and Microsoft Hyper-V.

Duplication by SLP is not something you can schedule from the console.

I will propose here two ways to workaround this matter Symantec didn't provide a tool for : one quite well known, and a new one, more elegant but also more discrete.

First Method - scripting

You can deactivate/reactivate SLP duplication operations by scripting the command line :

nbstlutil active -lifecycle <SLP_mySLP> | -backupid <This_backupid>

nbstlutil inactive -lifecycle <SLP_mySLP> | -backupid <This_backupid>

Getting the list of the SLP policies is just a question of nbstlutil list command, while working with the backupid can be more tricky if you want an automized solution.

There you will be able to deactivate all you SLP at night by a cron, a windows task, controleM or $Universe, whatever method is your favorite.

The session_notify and end_session_notify script may help organize the duplication moment too,...

In a coupe of days time I will have been looking after Backup Exec in some shape or form at Symantec for eleven years. Sales, pre-sales, regional technical leader and now as Subject Matter Expert. In that time I've known software and that's it, really. Certainly, like any pre-sales guy I could make the hardware do useful stuff but it was software driven.

 

So what's with backup appliances? Software and hardware in one go. Some time ago Symantec launched the first NetBackup appliance and with a series of appliances now available it seems that the business is going from strength to strength. But It's not like e-mailing a license key or buying boxed product software. There are incredibly slick processes being running in the background managing the logistics and I'm in awe of the people who make it happen. I'm lucky enough to call some of them friends. They do the hard work so you don't have to; but more of that later.

Cloud is the answer. It has to be doesn't it? And its all about software, right? Wrong. I'm at VMworld in Copenhagen this week and its not just about software and its not all about virtual. Sean Regan walked around the show and found 14 hardware boxes that weigh more than him. Cloud? Maybe - clouds aren't weighed down by steel boxes. Consolidation? Maybe. Some of its expansion, especially in storage, but shhh, don't tell anyone; its a secret.

 

From customers I've talked to here it seems to be all about doing more with existing hardware. Getting the cloud you want from the infrastructure you've got. That sounds like its a blend of physical and virtual, not just all about virtual. Symantec can take the hardware you've got today and help you build a cloud infrastructure on top of it in partnership with VMware. Once you've built that infrastructure, we'll help you protect it too. Can you imagine deploying a physical production...

Background:

NetBackup does not treat media and the contents of data (images) written to Virtual Tape Libraries (VTLs) any differently to real Tape Libraries.

A mile high view of the process after the 'expiry date' of each NetBackup image has passed :
- Removes the image from the image database
- Decrements the number of valid images on the media in question in the media database (a table within the EMM db since NetBackup 6).
- Once the number of valid images in the media db reaches zero, the 'assigned' field in the volume database (a table within the EMM db since NetBackup 6) is cleared
   Optionally the tape is moved back into the 'Scratch' pool (if configured).
   Note: It is best practice is to configure a Scratch pool.

Nothing in the above process touches either the media or library. For "real" libraries, the media can be out of the library and...

Thanks again for attenteding the latest user group meeting. And a BIG thank you to Geico for hosting this event.

As a follow up several of you had plenty of questions around the NetBackup Appliances. Below are links to more resources about our appliance story and the different models/sizes we offer.
